Description

ClientDeduplicationFailureTest.testClientDeduplicationCorrectnessWithFailure is flaky. It fails sporadically. It was disabled in https://github.com/apache/pulsar/pull/14509 because it was leading to out of memory errors. Ideally, we'll find a way to re-enable it without causing OOM.

Contributor guide

Research direction
Investigate the test ClientDeduplicationFailureTest to understand why it causes out of memory errors sporadically. Look at the test setup and production code for client deduplication to identify memory leaks or resource exhaustion. Focus on re enabling the test without OOM.
